A Particle (Mass = 5

question 66

Multiple Choice

A particle (mass = 5.0 g, charge = 40 mC) moves in a region of space where the electric field is uniform and is given by E_x = −2.3 N/C, E_y = E_z = 0. If the position and velocity of the particle at t = 0 are given by x = y = z = 0 and v_z = 20 m/s, v_x = v_y = 0, what is the distance from the origin to the particle at t = 2.0 s?

• A) 60 m
• B) 54 m
• C) 69 m
• D) 78 m
• E) 3.2 m
